Do you know if it is possible to configure MiVB SIP trunk to respond to incoming calls with "302 Moved Temporary" instead of sending INVITE request with Diversion header?
--> INVITE
<-- 100 Trying
<-- 180 Ringing
<-- 302 Moved Temporarily
Unfortunately our client decided to switch to a new SIP trunk provider and the new one requires this SIP signalling for diverted calls.
